How do you test the Ignition control module for a Nissan 300zx?

If you can start the engine when cold, but it sputters and stalls when it's warm, then you most likely have a bad ICM. When you crank the engine, if you have tachometer movement, then the module is good, if there's no tach movement while cranking then the module is bad. The tachometer gets the signal from the module, so if the tach works, then the module is good.


How do you adjust the idle RPM on 87 dodge raider?

From the driver's side fender, look at the carburetor. Near the bottom and towards the back, you will see two small Phillips-head screws. The upper (SAS1) and lower (SAS2) both control idle speed. LEAVE THE LOWER ONE ALONE!!! Start the truck and let it warm up to operating temperature. You'll need a tach that is visible from the engine compartment--I got mine at Sears for like $30. Anyway, the factory spec for warm idle is 700 +/- 50 RPM. Use the screwdriver to turn SAS1 (the upper of the two idle screws) until your tach shows revs in that range. That's it, you're done.
